Abstract: The process according to the invention is characterised in that the vanadium-containing catalyst component (1) is obtained by first (1.1), in a first step, (1.1.1) reacting an alkanol containing at least three carbon atoms and at least two hydroxyl groups and (1.1.2) an alkylaluminium compound in a liquid, inert hydrocarbon, giving a mixture of a solid and a liquid, then (1.2), in a second step, (1.2.1) reacting the solid obtained from step (1.1) and (1.2.2) a transition-metal compound from the series comprising certain vanadium compounds in a liquid, inert hydrocarbon, again giving a mixture of a solid and a liquid, and then (1.3), if necessary in a third step, separating, if desired washing and drying the solid from the mixture produced in step (1.2); and isolating the novel vanadium-containing catalyst component (1) in this way with the solid obtained as a mixture in step (1.2) or as a pure substance in step (1.3). The vanadium-containing catalyst component (1) allows very good regulation of the molecular weights of the polymers by means of hydrogen and has good productivity.
